Whats one of the most overlooked anti-flowing subaru pieces you
ask??...the stock exhaust manifold crossover. 50% of your exhaust
gasses are passing through this tiny tiny pipe and that is not good.
Well here comes the solution for this problem.
Welcome to our Version 2 Subaru Exhaust Manifold HiFlow Crossover. As
many of you may or may not know, we came out with our 1st Gen crossover
the end of last summer and had sold out of them instantly every time we
got a new batch in.
Well we've decided to step it up a notch with our first revision of the crossover. Meet HiFlow Crossover v2. Immaculate welds, smooth as butter 2" stainless steel, thick 12mm stainless flanges. you cant beat this piece.
Customers have seen up to 15 HP INCREASE when combined with our PnP Subaru Exhaust Manifold. This unit is built from 2" 304 Stainless Steel
throughout, maximizing exhaust flow from cylinders 1 and 4 to the
manifold collector for faster turbo response. This unit has a flex in
the center to allow for easier installation.
Add on our amazing Ceramic Heat Coating for a VERY SMALL fee to help keep
the heat in and speed up those exhaust gasses even more.
Boost transition is improved over stock
Helps airflow in the mid to high rpm range.
